53742614 divided by 39 
The aim is to understand the frequency of 39 in 53742614.

Going ahead to step 1:
39 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 39

Going ahead to step 2:
39 goes into 53 1 times with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 39 away from 53, we end up with 14.
Fetch the next digit (7) from the dividend, attach it to 14 and continue: 147 / 39

On to step 3:
If we divide 147 by 39, we get 3 and a remainder of 30.
The next digit of our result is 3. 
Result so far: 13.0
If we subtract 117 from 147, we get 30.
Take the next digit (4) from the dividend and append it to 30, then repeat: 304 / 39

Let's proceed to step 4:
39 goes into 304 7 times with a remainder of 31.
Record the quotient 7 as the next digit in the result. 
Result so far: 137.0
The remainder is 31 after subtracting 273 from 304.
Take the next digit (2) from the dividend and append it to 31, then repeat: 312 / 39

On to step 5:
If we divide 312 by 39, we get 8 and a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 1378.0
The remainder is 0 after subtracting 312 from 312.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 39

On to step 6:
39 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 13780.0
Subtract 0 from 6 to get 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 39

Moving on to step 7:
When dividing 61 by 39, we get 1 with a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 137801.0
If we take 39 away from 61, we end up with 22.
Include the next digit (4) from the dividend after 22, then repeat: 224 / 39

Moving on to step 8:
39 goes into 224 5 times with a remainder of 29.
Record the quotient 5 as the next digit in the result. 
Result so far: 1378015.0
If we subtract 195 from 224, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 9:
When dividing 290 by 39, we get 7 with a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 1378015.7
The remainder is 17 after subtracting 273 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 10:
170 divided by 39 is 4 with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 1378015.74
Deduct 156 from 170 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 11:
When dividing 140 by 39, we get 3 with a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 1378015.743
Subtracting 117 from 140 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 12:
If we divide 230 by 39, we get 5 and a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 1378015.7435
Subtract 195 from 230 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 13:
If we divide 350 by 39, we get 8 and a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 1378015.74358
Subtract 312 from 350 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 14:
380 divided by 39 is 9 with a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 1378015.743589
The remainder is 29 after subtracting 351 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 15:
39 can be fit into 290 7 times, resulting in a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 1378015.7435897
If we subtract 273 from 290, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 16:
39 goes into 170 4 times with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 1378015.74358974
Deduct 156 from 170 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 1378015.74358974 and a remainder of 1.4e-08.
